I think people are being naive in counting out a 5 inch iPhone based on Cook's comments.
What he is really doing is setting up the eventual reveal of such a phone.
Look at his statement:
"Our competitors have made some significant tradeoffs in many of these areas to ship a larger display. We would not ship a larger display iPhone while these tradeoffs exist."
When they do announce it, they will first start talking about all the advancements they've made to the screen technology. They will then compare how lousy these big Android screens look. Then they will finally reveal they have made a 5 inch screen without all those tradeoffs, with the iPhone 6 having the best 5 inch screen on the market.
It's a classic Steve Jobs play.
